  Purpose

This is a Phase IIIB, randomized, prospective, multicenter, single-country, open-label, controlled pilot trial designed to evaluate the effect of infliximab induction therapy on sustained virologic response (SVR) to treatment with pegylated interferon alfa-2b plus ribavirin in a group of 96 therapy-naïve subjects with genotype 1 hepatitis C virus (HCV) infection and high serum tumor necrosis factor (TNF)-alpha values.
